Airport loses signal every few days

Question

Hi there, I have an airport express which I love, but recently it keeps losing its signal. My ibook and both my mom and dad's ibooks will not detect our airport. I tried changing our channel so it doesn't interfere with our neighbor's networks, which usually works too, but basicallly every 2-3 days, our signal dies. I usually just unplug the airport, and plug it back in after 30 sec. and that works, but its getting annoying. Any thoughts? I'm really tired of our signal being interrupted.

This has started happening to me on a daily basis.
I would like some help/answers too.
Hi Jeffrey Eddy!
So far during 2007 there have already been one major OS X update and several Security Updates that may have closed holes that might have existed in wireless operations/configurations, or may have made other changes. We don't know for sure, as most of that infomation is typically not made public.
To conform your system to these changes, you will want your base station's firmware to be up-to-date, and your OS X version to be up-to-date. It sounds as if your AirPort Express firmware might not be up-to-date. As anything older will lead to a problem of some sort, it should have the current version 6.3, linked HERE. You can check what your current version is by opening the utility "AirPort Admin Utility" and it will be listed below the Express photo, at the bottom right, as "Apple Base Station V."
Using the Network panel of System Preferences, it also wouldn't hurt to delete and block access to all other wireless networks other than your own that are listed on the AirPort/AirPort pane in the "By default, join:" selector which is located in the middle of the pane.
Rename and reconfigure your own network while you're at it. For that, use "Network Setup Assistant" which is opened at the bottom of the Network panel by using the "Assist me..." button followed by the blue "Assistant..." button. First name your network configuration - you're not naming the network, but the new configuration name that will be displayed on the Network panel's "Location:" selector. Continue on, and in response to "How Do You Connect to the Internet?" activate the radio button for "I use AirPort to connect to the Internet wirelessly." And continue on until you've completed setup of the new network configuration.
Before I switched my setting it woud just randomly
jump to a weaker network signal in the middle of
work.
The default setting of your AirPort is: "If no recent networks are found: Ask before joining an open network." Therefore, your AirPort could only have jumped to another network signal if you had edited the default setting, or due to your willingness to trespass onto the wireless networks of others, which has the same effect. Using someone else's unencrypted network to make online purchases is a good way of becoming a victim of identity theft, if you like that sort of thing.
I always get the warning "connection to base station
not found" so I think it's either the Express itself
or the Airport.
It's probably neither, but a faulty configuration on your part, or due to lack of current firmware in the Express.
I also have an Xbox360 logged into
Live constantly (direct wired through a gateway) and
I never have a service interuption.
This would have nothing to do with your wireless issues.
I have heard a rumor that air traffic can disrupt
wireless service. Is this true? I live about 5 mi.
from Port Columbus.
No, not true. Since most of the population of the country, if not the world, is within 5 mi. of an airport or air traffic, how would all the wireless cell phones work?
Kindly refer to the Apple Support article: AirPort: Potential sources of interference
